v DRIVING DEVICE FOR GUN .EL VATING AND TRAINING GEARS.

To all whom it may concern:

Be it known that I, HANS STRAUSS, reslding at Essen-on-the-Ruhr,Germany, a subject of the Emperor of Germany, have invented a certainnew and useful Improvement in Driving Devices for Gun Elevating andTraining Gears, of which the following is a specification.

This invention relates to a driving device for elevating and traininggears for guns, and more particularly to such devices as are providedwith two driving mechanisms of which each has two hand wheels and twodriving shafts simultaneously operated by one man.

The subject matter of the present invention resides in an lmprovement 1ndrlvlng devices of this kind, wherein not only each through the handwheels, and Fig. 3 a section on line 38 of Fig. 2 Seen from the left.

The arrangement illustrated in Figs. 2'

and 3 will first be described.

In a two piece housing A are mounted two shafts B and C in coaxialbearings, which shafts each have a hand wheel 6 and 0 respectively. Onthe shaft B is secured .a bevel wheel D which is in mesh with a bevelwheel E carried by a hollow shaft 6 mounted in the housing A. The shaftC carries a bevel wheel G which is inmesh with another bevel wheel H,the former of which is revoluble, but axially non-displaceable on shaft0 and the latter bevel wheel I-I isrigidly secured on a shaft k which iscoaxial with the hollow shaft 6 A coupling muff K is arranged on theshaft C between the bevel wheels D and G, which coupling muff is axiallydisplaceable but non-revolubly' connected with the shaft C by means ofkey (2 and groove 79 The muff Kcarries on each side claws k and 70respectively, which are intended to cooperate with correspondinglySpecification of Letters Patent.

shaped claws al g on the bevel wheels D, G,

respectively, in the manner of a claw coupl ng. The muff K 1sfurthermore provided with an annular groove 70 engaging with twotrunnions Z of a fork-shaped lever L.

This lever L is non-revolubly mounted onv a V shaft M which is carriedin bearings a and a in the housing A and is provided with a handle mThis handle may be held by means of a dog (not shown) in two positionswherein the muff K is in engagement with one of the bevel wheels D andG. In the drawing the muff K is represented in its idle position.

Fig. l are shown two of the described driving mechanisms designated withI and II which serve as driving devices for the two directing gears ofthe gun. The shafts e and h of the two mechanisms are therein connectedin the following manner with the directing gears. The shaft 6 of thedriving mechanism I and the shaft 71 of the driving mechanism II havegearing connection with the elevating gear of the gun. The elevat- 'inggear comprises a toothed are N secured to the cradle of the gun mount,and this toothed arc is in mesh with a gear wheel N wh1ch is mounted inbearings in the body of the carriage. The connection of the shaft 6 ofthe driving mechanism I with the gear wheel N is accomplished by meansof a 'N The shaft k of the driving mechanism II has gearing connectionwith the shaft 6 and consequently also with the elevating gear by meansof a pair of bevel wheels H a shaft 7L and a second pair of bevel wheelsH The-shaft h of the driving mechanism I and the shaft 6 of thedrivingmechanism II are moreover in gearingconnection with the training gear.The training gear comprises a worm P, which is in mesh with a toothedcircle P on the carriage body. The connection of the shaft h of thedriving mechanism I with the shaft 79 of the worm P is accomplishedbymeans of a pair of gear wheels H while between the shaft 29 and theshaft 6 of the driving mechanism II are inserted two pairs of bevelwheels E and E 7 If the two driving mechanisms, together with thenecessary sighting device B, Fig. 1,

can be used, and if besides a suflicient number 0t cannoneers areavallable the muflf K Wlll be so adjusted in both of the drivingmechathe greatest pOWG1',fi;l1 Lt means, with the greatest possiblespeed. The parts 7L H and G of the driving device II will then run idlein driving the elevating gear and the same parts of the drivingmechanism 1 will run idle in driving the training gear.

Should one of the two driving devices be inoperative for instance inconsequence of covering the sight field of the corresponding sightingdevice R through the shield of the mount; or in consequence of thedisabling of the serving cannoneer, the two directing gears may then beoperated from the single useful driving mechanism. The mufi K of saidmechanism will then have to be so ad justed that its claws 70 are inengagement with the claws g of the bevel wheel G. The hand wheel I) isthen connected with one of the directing gears by means of the bevelwheels D and E and shaft 0 and the hand wheel 0 in gearing connectionwith the other directing gear by means of parts C, K, G, H and M.

I claim 1. In a gun directing mechanism, having both elevating andtraining gears, two sets of driving mechanisms, each operable by one manand each comprising a pair of hand wheels; the first of said hand wheelsin the first set of said driving mechanisms having permanent gearingconnection with the ele vating gear; and the first of said hand wheelsin the second set of said driving mechanisms having permanent connectionwith the training gear; and coupling means in each of said sets ofdriving mechanisms, said coupling means constructed to connect thesecond of said hand wheels in either of said sets of driving mechanismswith the first of said hand wheels in the same, or the first of saidhand wheels in the other of said sets of driving mechanisms; whereby theelevating gear may be operated by both wheels in the one set, and thetraining gear by both wheels in the other set; or the elevating gear byone hand wheel and the training gear by the other hand wheel in the sameset of driving mechanisms.

2. In a gun directing mechanism, having both elevating and traininggears, two sets of driving mechanisms, each operable by one man and eachcomprising a pair of hand wheels; the first of said hand wheels in thefirst set of said driving mechanisms having permanent gearing connectionwith the elevating gear; and the first of said hand wheels in the secondset of said driving mechanisms having permanent gearing connection withthe training gear; a coupling means in each of said sets of drivingmechanisms; said coupling means comprising a shaft for the second handwheel, a gear wheel running loose on said shaft, a mufi' keyed to slideon said shaft, claws on both ends of said muff and corresponding clawson said'gear wheel and on an adjacent part of the permanent gearingconnection respectively, a shifting lever adapted to hold said muff ineither of its three positions, viz. first idle position, second inengagement with said gear wheel or third in engagement with saidpermanent gearing connection; said gear wheel in one of said sets ofdriving mechanism being constantly in engagement with the permanentgearing connection in the other of said sets of driving mechanisms;whereby the elevating gear may be operated by both wheels in the oneset; and the training gear by both wheels in the other set; or theelevating gear by one hand wheel and the training gear by the other handwheel in the same set of driving mechanisms.
